In this paper, the tracking control law design problem for a class of polynomial fuzzy systems subjected to external bounded disturbance is studied. The tracking control design problem is solved using the observer‐based tracking controller design method in which the observer estimates the controlled system state vector and also the system states will follow the state vector of a stable reference model subject to an H ∞ performance. The process of calculating controller parameters is formulated as an SOS feasibility program. Simulation results are presented to show the merits of the proposed control design approach.
